Gillibrand, who will defend her seat for the first time since being named by Gov. Paterson to complete Hillary Clinton's term, leads former Rep. Joe DioGuardi 51% to 28% and attorney Bruce Blakeman 51% to 31%. The incumbent Democrat earns 46% support against economist David Malpass, who gets 27% of the vote.
In the three match-ups, those who prefer some other candidate in the race range from 7% to 10%. Another 10% to 16% are undecided, Rasmussen found in a telephone survey of 500 likely NY voters on May 12.
Just last month, Gillibrand's position was seen as far less stable: She had 40% support against a "generic" Republican candidate who picked up 39% support.
Gillibrand's still got work to do, however: She "barely edges all three Republicans among male voters, but holds substantial leads among female voters," the poll found.
Overall, about 18% of New York voters hold a very favorable opinion of Gillibrand, while 20% view her very unfavorably.

Among the Republican contenders, the poll found 6% view DioGuardi very favorably and 12% view him very unfavorably.

Blakeman is seen very favorably by 3% and very unfavorably by 11%.
Just 1% have a very favorable view of Malpass, while 10% regard him very unfavorably.
About 7% have no opinion of Gillibrand, suggesting that she's getting her name out there a lot more.
The Republicans, however, seem to be a bit behind on the "getting to know you" portion of the show: Anywhere from 38% to 44% of NY voters don’t know enough about the GOP candidates to express any kind of opinion of them.
